As a non-American I haven’t really been following these mid-terms, but what do the current results suggest the USA will have as president in two years time? A Giant Douche, or a Turd Sandwich?
What the midterms say to me is that the Republican brand has been decisively weakened by Trumpism - the crazier wing of the party was trounced in all but the most crazy of districts (where someone like MTG can win decisively). Moderates, by and large, are running from the party.
The smarter, younger version of Trump is DeSantis (who I'd say is the Giant Douche), and he won in a landslide in Florida, which was only surprising in the sheer magnitude of the win. If I were a Republican, I'd want him to win the nomination in 2024 - he could successfully con enough people in the middle in swing states to vote for him.
However, Republicans pick their candidates in primaries, and Trump's base is so large, vile and quite frankly, stupid enough to keep voting for him. He's the Turd Sandwich. It's very possible he will be the nominee again in 2024. Because there is no way his ego will let him cede control of the party to someone else.
On the Democratic side, literally no one wants Biden to run again - but there is no clear party- and county-unifying option to take the helm. The midterms tell me that most Americans want some semblance of normalcy more than anything else. So if it's an 80 year old Biden again, and he's the best (only) option to keep us from going down the rabbit hole, then so be it. Midterms usually go against the presidency, so these midterms show me, if nothing else, Biden is not nearly as toxic as the media wanted us to believe.
